The student Chromebooks do not come with cases. It is recommended but not required that you purchase something to protect your device.
Our buildings don't allow backpacks in the classroom so the student should not expect to be able to use a backpack for the purpose of carrying their Chromebook between rooms.
We recommend cases specifically designed for Chromebooks. Sleeves are acceptable but will not provide much drop protection.
